films that did drop indicated much smaller deses than those films which
remained above ground.
Although the tire of dropsing is unknown, the
films might reasonably be assumed to have dropred before the arrival of
fallout.
Only the dropped-film data are presented with error limits wnien
do not include the error due to dropping time.
No neutron corrections are
presented since the neutron flux was negligible.

OPERATION UPSHOT-KNOTHOLE

(U) Operation Upshot-Knothole was conducted at the NTS from March to
‘

June 1953.
The operation consisted of 11 detorations highlighted by Shot
10, which was an atomic weapon fired from a cannon.
The pertinent she

information and meteorological data are given in Tables 3.47 and 2. LS

respectively.
It should be noted that in some of the WT reporss For this

UXS-ROTInitial gamma measurements were made by LASL

(Reference 35)

for Shots 5, 6, 10, and 11 and by SCEL (Reference 36) for Shots 1, 2, 3,
5, 6, 7, 8, 9, and 10. The SCEL gamma detectors consisted of five film
types encased in NBS holders and attached to aluminum staxes assumed to

be 1/4-inch thick.

The film range was from 0 to 12,000 r.

The detectors

were recovered approximately 3 hours arter detonation.
No azimuth is
given for Shots 1, 3, 6, and 9, and no mention is made of corrections
